American Suspension Stoppie King™ Brakes – Made in USA


The standard motorcycle brake caliper has a basic problem. The thing is necessarily shaped like the letter “C” with the force of the pistons exerted on the top and bottom of the letter. This force spreads the caliper apart like opening a book. The result is that some of the force generated by the master cylinder is wasted, actually in spreading the caliper. The inevitable result is increased lever travel and tapered pad wear.

Caliper designers spend a lot of time trying to minimize this deflection. Some try variable piston sizes to minimize tapered pad wear. Others use cute calipers and hope you don't really care about performance.

Enter the Stoppie King™.

The Stoppie King™ uses Monoblock construction , means the entire caliper is made from a single block of aircraft aluminum. The Stoppie King uses six 1" diameter pistons. The Stoppie King™ uses twin bleeders so you can quickly remove every single bubble of air from the system before you trust your life to your brakes.


B-62 Monoblock Six™ piston brake caliper, with radial mounting

The caliper comes complete with banjo bolt and high strength cone type internal wrenching mount bolts.  The bolts are ½” bolts much stronger than the bolts overseas calipers come with.


6 piston vs overseas 4 piston


Monoblock vs everyone elses flexi flyer two piece caliper.


The M6™Monoblock design gives you  maximum braking power.  Bolted together calipers flex and distort under load.  The M6 is a rigid solid block.   No squishy lever – just solid braking power.


The Monoblock design means a distortion free caliper eliminating the need to compensate for weak caliper design with differential bore.  Every M6™ piston lays down full force on the brake rotor.


The Monoblock Six™ features brake bleeder screws, strategically placed to give you fully bleed caliper quickly and easily.


The Monoblock Six™ six-piston design distributes braking power to the pad over a very wide surface,  Giving you maximum brake power.


The Monoblock Six™ is available in a variety of finishes to colmplement your bike
